DI: digital input; M2: ground reference; M: electronic ground
Max. connectable cross-section: 1.5 mm² (AWG 14)
NOTE
An open-circuit input is interpreted as "low".
Terminal M1 must be connected so that the digital inputs can function correctly.
The following solutions are possible:
1) The provided ground reference of the digital inputs, or
2) A jumper to terminal M (Important: electrical isolation for the digital inputs
is revoked as a result).

CAUTION
The input current of the analog inputs must not exceed 35 mA when current
measurements are performed.
